Substitutions during live matches

[Tactician]

There are probably many threads about this issue, so I am commenting in one instead of creating another thread because the susbtitutions problem is back. Lately, substitutions are either happening late or not all until another change is made and saved during live matches. The latest example is in latest event match I did today before commenting here wherby I made a substitute before half-time but the substitution was done like 20 minutes into the second half.
